Two Novel Flip Flop With Level Triggered Reset in Quantum Dot Cellular Automata

Quantum dot cellular automata (qca) introduces a pioneer technology in nano scale computer architectures. employing this technology is one of the solutions to decrease the size of circuits and reduce power dissipation. in this paper, two new optimized flipflops with reset input are proposed in quantum dot cellular automata technology. in addition, comparison with related works is performed. the reset pin in the proposed circuits is level triggered. simulation results demonstrate that both proposed desgins have efficient structures in terms of area, delay and complexity. the proposed structures are simulated using the qca designer and validated. simulations of the first proposed level triggered reset d-flip flop showed that this circuit has 82 quantum cells and required only two clock cycle for valid operation. in addition, the second proposed architecture for level triggered reset d-flip flop has only 85 quantum cells and it needs only one clock cycle for proper operation.
